From Dance Dance Revolution (a.k.a. DDR); One More Extra Stage. "Dance Dance Revolution" (the name is the title of the OMES song, as well as the game itself.) The song is played with modifiers Dark (visual landmarks for timing are invisible), Reverse (the arrows, normally scrolling from the bottom-up, now scroll from the top-down), 1.5x (the arrows scroll 1.5 times faster than usual), and Sudden Death (one No Good/NG or non-combo step (good, boo, miss) ends the song).

Acquired by getting a AA on the default Extra Stage song The Legend of MAX, which is played using modifiers Dark, Reverse, 1.5x, and No Recover (the life bar, which usually starts at about 1/2 full and grows with the player's score, starts at full strength, and the player cannot add to this bar; only lose from it).

Other than the definition:
Oh My Edward
(a now common alternative for OMC- oh my Carlisle)
which refers to the Twilight Books and Movies
OME can also stand for Oh My Earth
used by people who can be seriously against blaspheming or just by people who don't want to say god. bit like Oh My Goodness.

1. Oh My Edward
Girl 1: Did you see New Moon yet?
Girl 2: OME of course, Edward is sooo hot in it.

2. Oh My Earth
Guy: they want to cut all the trees down
Girl : OME! They can't!
